I just got an '86 too. [See my post above about the starter reduction gears].
I paid $1000 for mine, and it seems to run great, except for the starter. It has some clunking noise that comes from the front end when in reverse, and I have heard that is sort of normal for this model. Is that true? I doesn't seem to cause any problems and doesn't clunk or grind when riding, just when the wheels are turned going in reverse.
Here's some pics.
